To this end, anchorage straps 17 may be passed about the two mattresses and tightly secured thereto.

Two rails 18 extend crosswise of the bed and are secured to the under side of the ends of the plate 10 of the submattress. They may also be suitably secured to other parts of the submattress but are desirably supported solely by the spring structure of the submattress. These rails are spaced apart a distance about equal to the length of the.

openings in the mattresses and constitute a runway extending beneath said openings. The rails are desirably of Z-form and are so assembled as to present two inwardly project'ing ledges upon which the rim of a veslsel 19 may be placed. Such vessel has a handle 2() lby which it may be moved into register with the openings in the two mattresses 'or removed from the bed. Before the vessel is placed upon the rails in position beneath said`openings,the liller 12 is removed from the opening in the'supermattress that it normally occupies. In order that the filler may kbe conveniently removed and restored I provide operating lever mechanism therefor. 'I he lever mechanism illustrated is inclusive of a link 21 which is pivoted at one end to a bracket 22 which is carried by and depends from the plate 13. The plate 13 is also shown appropriately hinged as at 22a by the hinge members 22?) (suitably secured to the plate) to a member 220 carried by and secured transversely ofthe rails 18. Another link 23V is connected with the link 21, at one end, and is secured at its other end to a rod V24 which is journaled in brackets 25 that are carried by and depend from the rails 18. The link 21 has its lower end upturned and there carries a pin 26 which bears upon the top of the link 23 and vnormally maintains the center ofconnection of the twowlinks below a straight line containing the pivotal centers of the links. The connection between of the bellcrank, the link '23,' and the arm i 28 being pivoted to the other lever of the bellcrank, the arin 27. The lowery edge of the arm 28 is formed with two notches 29 and 30 which are adapted to receive a retaining pin 31 which is vcarried by thezbracket 32 which isv provided upon and depends from one of lar extension 33 by which it may be manipulated. When the arm 28 is in the position shown in Fig. 5, the filler section 12 of the supermattress is in position. When said arm is moved inwardly to a position in which the notch 30 receives the pin 31, the filler is swung downwardly and sufficiently out of register with the openings in the two mattresses to permit the vessel 19 to be moved into register with such openings and out of register therefrom.' The link I21 is desirably a double link whose parts are joined by the pin 26, the single link 23 being received between the lower ends of the two parts of the double link 21 as is clearly illustrated.

Changes mcy'be made without departing from the invention.

Having thus described my invention, I claim:l

In a bed for invalids, a sub-mattress adapted to carry a separable super-mattress having an opening therethrough in a mid-portionthereof, said sub-mattress comprising a frame; a spring structure carried by the frame and adapted to provide a cushion support for the super-mattress; an aperture in the spring structure for registering with the opening in the super-mattress; a pair of parallel rails carried by the spring structure and extending transversely of the submattress on each side'oi:` said aperture; a filler support pivoted on said spring structure transversely of therrails at one side of the aperture; a ller on said filler support for the opening in the super-mattress; brackets depending from said rails; a rod journaled in the brackets and extending laterally beyond the rails; a link rigidly secured to the rod mid-way thereof and extending upwardly therefrom; another link pivoted to the first link and to the Jiller support substantially centrally thereof; a lever rigidly connected to one end of the rod and extending upwardly therefrom; an arm pivoted to the upper end of the lever and extending parallel with said rails toward a margin of the sub-mattress, said arm being movable transversely of the sub-mattress; a bracketfcarried by the sub-mattress for slidably carrying the outer end of the arm a handle on the arm between the bracket which carries the arm and the margin of the sub-mattress; and a separable vessel slidably supported by said rails.

' In witness whereof, I hereunto subscribe my name.
